+ * Phase 1.5 Task 1.5.2: End-to-End Workflow Tests
+ *
+ * This test suite validates complete user journeys from blank form to exported YAML.
+ * These tests ensure that users can successfully:
+ * 1. Create a minimal valid session from blank form
+ * 2. Create a complete session with all optional fields
+ * 3. Add and configure all major components (experimenters, subject, cameras, tasks, etc.)
+ * 4. Trigger ntrode generation
+ * 5. Successfully validate and export YAML
+ *
+ * These workflows were marked as complete in Phase 1 but were not actually tested.
+ * This fills a critical gap in test coverage for real user workflows.
+ *
+ * SOLUTION: ListElement fields CAN be queried by placeholder text!
+ * - Cannot use getAllByLabelText() because input lacks id attribute
+ * - CAN use screen.getByPlaceholderText() - each field has unique placeholder
+ * - After typing, press Enter to add item to list
+ *
+ * Verified with test_listelement_query.test.jsx ✓

+ *
+ * ID Management:
+ * - If arrayDefaultValue has id field: auto-increment from max existing ID
+ * - Starts from 0 if array is empty
+ * - Increments by 1 for each new item
+ * - Example: existing IDs [0, 1, 2] → new items get IDs [3, 4, 5]

+ * @file App-duplicateArrayItem.test.jsx
+ * @description Tests for duplicateArrayItem function in App.js
+ *
+ * Function: duplicateArrayItem(index, key)
+ * Location: src/App.js:680-705
+ *
+ * Purpose: Duplicate an array item and insert it immediately after the original
+ *
+ * Behavior:
+ * 1. Clones formData using structuredClone
+ * 2. Clones the item at form[key][index]
+ * 3. Guard clause: return if !item (invalid index)
+ * 4. Auto-increments ID if item has 'id' or ' id' field (case-insensitive)
+ * 5. ID calculation: maxId = Math.max(...all IDs in array), newId = maxId + 1
+ * 6. Uses splice(index + 1, 0, item) to insert duplicated item after original
+ * 7. Updates formData state
+ *
+ * ID Field Detection:
+ * - Checks object keys for 'id' or ' id' (case-insensitive)
+ * - Converts key to lowercase for comparison
+ * - Preserves original key casing when setting new ID
+ *
+ * Splice Insertion:
+ * - splice(index + 1, 0, item) means:
+ * - Position: index + 1 (right after original)
+ * - Delete: 0 items
+ * - Insert: item

+ * Tests for YAML.parse() error handling in importFile()
+ *
+ * Phase 3, Task 3.3 - CRITICAL BUG FIX
+ *
+ * KNOWN BUG: importFile() clears form BEFORE parsing YAML (line 82)
+ * If YAML.parse() fails (line 92), form is already cleared = DATA LOSS
+ *
+ * Location: App.js lines 80-154
+ *
+ * Critical scenario:
+ * 1. User has filled out complex metadata form (30 minutes of work)
+ * 2. User tries to import a reference YAML file
+ * 3. YAML file is malformed (syntax error, encoding issue, etc.)
+ * 4. YAML.parse() throws error, crashes app
+ * 5. Form is already cleared (line 82) - ALL DATA LOST
+ *
+ * Required fix:
+ * - Add try/catch around YAML.parse()
+ * - On error: restore form to defaults (or previous state)
+ * - Show user-friendly error message
+ * - Prevent data loss

+ *
+ * This function is triggered when a user selects a device_type for an electrode group.
+ * It auto-generates ntrode channel maps based on the device type and shank count.
+ *
+ * Key behaviors:
+ * 1. Sets device_type on electrode group
+ * 2. Generates ntrode objects (one per shank) with channel mappings
+ * 3. Removes old ntrode maps for this electrode group
+ * 4. Adds new ntrode maps to formData
+ * 5. Renumbers all ntrode_id values sequentially (1, 2, 3, ...)
+ *
+ * Architecture understanding:
+ * - deviceTypeMap(type): returns channel index array [0, 1, 2, 3] for map structure
+ * - getShankCount(type): returns number of shanks (determines # of ntrodes)
+ * - Each shank gets ONE ntrode object
+ * - ntrode.map: { 0: 0, 1: 1, 2: 2, 3: 3 } with offsets for multi-shank
